DISCUSSION
TODAY THROUGH MONDAY...
A BROAD LOW PRESSURE SYSTEM WILL BRING COOLER AND UNSETTLED
WEATHER TO THE AREA TODAY INTO THURSDAY.
THE INITIAL COLD FRONT ASSOCIATED WITH THE LOW PRESSURE SYSTEM IS
MOVING THROUGH THE AREA THIS AFTERNOON AND IS EXPECTED TO MOVE
EAST INTO NORTH DAKOTA AND SOUTH DAKOTA BY MID-AFTERNOON. WITH
THIS, BREEZY WESTERLY WIND GUSTS IN THE 20S AND 30S MPH ARE COMMON
ALONG AND BEHIND THE COLD FRONT. SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS ARE EXPECTED TO DEVELOP BEHIND THE COLD FRONT AS
WELL TODAY AND MOVE EAST THROUGH THE AREA THIS AFTERNOON AND
EVENING. WHILE THE POST- FRONT ENVIRONMENT WILL NOT FAVOR STRONG
TO SEVERE THUNDERSTORMS, STEEP LOW LEVEL LAPSE RATES MAY ALLOW FOR
THUNDERSTORMS CAPABLE OF PRODUCING BRIEF GUSTY WINDS, SMALL HAIL,
AND MODERATE RAIN (15 TO 40 PERCENT CHANCE OF LIGHTNING, GREATEST
OVER SOUTH- CENTRAL MONTANA). LOOK FOR SHOWERS AND THUNDERSTORMS
TO DECREASE IN COVERAGE LATE THIS EVENING INTO TONIGHT.
THE STRONGEST SYNOPTIC WINDS ASSOCIATED WITH THE LOW PRESSURE
SYSTEM ARRIVE WEDNESDAY. WITH THIS, WIDESPREAD WIND GUSTS IN THE
20S TO 40S MPH ARE FORECAST, STRONGEST OVER THE FOOTHILLS WEST OF
BILLINGS WHERE OCCASIONAL GUSTS INTO THE LOW 50S MPH ARE POSSIBLE
(50 PERCENT CHANCE AROUND BIG TIMBER AND 70 PERCENT CHANCE AROUND
HARLOWTON). WEDNESDAY NIGHT INTO THURSDAY MORNING, THE WINDY
CONDITIONS WILL CONTINUE, THOUGH THE STRONGEST WINDS WILL
GRADUALLY SHIFT EAST THROUGH TIME. THURSDAY AFTERNOON AND EVENING,
THE WINDS WILL DECREASE ACROSS THE AREA AS THE LOW PRESSURE
SYSTEM EXITS THE AREA.
ALONG WITH THE WIND, THE CHANCE OF PRECIPITATION CONTINUES
WEDNESDAY INTO THURSDAY. ON WEDNESDAY, ANOTHER ROUND OF SCATTERED
SHOWERS AND ISOLATED WEAK THUNDERSTORMS IS FORECAST NEAR THE
MONTANA AND WYOMING STATE LINE DURING AFTERNOON AND EVENING. WHILE
DRIER CONDITIONS ARE EXPECTED AROUND AND NORTH OF BILLINGS,
ISOLATED SHOWERS AND WEAK THUNDERSTORMS ARE ALSO FORECAST LATE IN
THE AFTERNOON INTO THE EVENING WITH CYCLONIC FLOW ALOFT. LATE
WEDNESDAY INTO THURSDAY, A SECONDARY PIECE OF ENERGY ON THE BACK
SIDE OF THE LOW PRESSURE SYSTEM WILL BRING ANOTHER ROUND OF
SCATTERED TO WIDESPREAD LIGHT SHOWERS TO MUCH OF THE AREA. WHILE
THE CHANCE IS LOW (5 TO 15 PERCENT), EMBEDDED THUNDER IS POSSIBLE.
TODAY THROUGH THURSDAY, TEMPERATURES WILL BE COLD ENOUGH TO ALLOW
FOR SNOW SHOWERS IN THE MOUNTAINS (GENERALLY ABOVE 8000 FEET,
THOUGH SNOW LEVELS MAY DROP NEAR 7000 FEET TONIGHT). WITH THIS,
SNOW SHOWERS MAY IMPACT MOUNTAINS RECREATION AND TRAVEL AT TIMES.
THIS INCLUDES TRAVEL OVER THE HIGHEST ELEVATIONS OF THE BEARTOOTH
HIGHWAY IN THE BEARTOOTH MOUNTAINS AND HIGHWAY 14 THROUGH THE
BIGHORN MOUNTAINS.
WHILE CONDITIONS TREND DRIER AND WARMER FRIDAY, ENSEMBLE
FORECASTS SUGGEST ADDITIONAL WAVES OF ENERGY WILL DROP INTO THE
AREA FROM THE NORTHWEST THIS WEEKEND INTO EARLY NEXT WEEK,
BRINGING COOLER TEMPERATURES AND THE CHANCE OF PRECIPITATION BACK
TO THE AREA. LA
